Doom fans looking to squeeze more life from Doom II, technologically resistant to joining us in the 21st century, can still see some of Rapture's underwater delights, thanks to this BioShock-inspired "demake" crafted for id Software's classic PC shooter.

That free-to-download Doom homage, curiously enough, comes from BioShock 2's lead level designer. JP LeBreton posted the personal project, created hot on the heels of the arrival of the 2K Marin-created sequel, on his web site. LeBretron was responsible for Arcadia and the Farmer's Market, the sections of BioShock on which he was the primary designer.

The map maker, also responsible for the Pac-Man reference in the original BioShock, offers detailed notes about the Arcadia demake in his developer commentary, packed with insider knowledge about the game's creation and its backward journey to Doom II. A great read for the BioShock fan but a Doom II level of still-unknown enjoyment.
